Excellent optics for an achromatic refractor. Stars are sharp across a 35mm frame. Some chromatic abberation but this is significantly reduced with a Baader UHCS filter - to the point of being hardly detectable.

For visual use very sharp but some chromatic abberation is present (not dissimilar to a C102 f10 refractor which I also own). The chromatic abberation is not very noticable at lower magnifications - excellent widefield scope. Good detail on planets despite chromatic abberation at high power (agree 375x is no problem) - awaiting a Baader semi-apo filter.

Bought one new, loved it, but like an idiot, sold it, then bought another (used) one because I missed the first one so badly. Love this scope. 2" longer than the Vixen 102 achromat, and only a little heavier, but SOOO much more capable. Goes MUCH deaper. Color on Jupiter is minimal (but more thant the Vixen 102 by comparison) but much more detail available in the larger 140mm Aperture. Stunning wide field of view with 35mm Panoptic. First one was a tiny bit better optically than the second one, but both are by most standards, quite excellent. Does everything exceptionally well and far more managmeble than a 6" f/8. I don't penalize it for color, because it is not sold as an APO. Only costs keeps me from giving it a 10. One of my favorite telescopes ever.

I purchased as a 2nd from Orion at a very discounted price of $1,680. Based on just two nights use. Stars were very tack sharp, a notch better than that of my Televue Genesis. Beautiful wide field views with 32mm TV plossl. The most stars I've seen in M42 with a refractor. I saw Jupiter's moon Lo come around the planet. Only purple halo was around Jupiter - nothing around any stars or Saturn. It didn't effect view of the planet itself. Telescope easily took power of 375x, and that is with basic 1.25" Meade diagonal. Unfortunately scope is set up for 1.25" eyepiece/diagonal and a $40 2" Vixen adapter is needed to correct it. The ota is light and just under 14lbs. Great scope paired with a Losmandy GM8. I love it.
